8 Page 8 CR:110A dosebadge User Manual Section 1 Introduction Thank you for purchasing the dosebadge Personal Noise Dosemeter System from Cirrus Research plc. The dosebadge is a unique solution to the problems associated with the measurement of Personal Noise Exposure. The dosebadge itself has no controls or cables which means that the unit can be used in situations where the wearer is working in confined spaces or where there is a risk of a cable being caught in machinery. Measurements are downloaded from the dosebadge to a Reader unit via an infra-red link which removes the need for keys or controls on the instrument. This version of the dosebadge, the CR:110A and the RC:110A Reader Unit, provide a range of configuration options which allow the system to be used to measure and record noise levels to most Occupational Noise and Industrial Hygiene Regulations. The CR:110A dosebadge and RC:110A Reader Unit, when used with the NoiseTools software, provide Dual Channel Measurements. Channel 1 can be configured to be any combination of the Exchange Rate (Q), Criterion Level (CL), Criterion Time (CT), Threshold (TH) and Time Weighting (TW). Channel 2 is preset to a 3dB ISO configuration as shown below: Parameter Configuration Options Channel 1 Channel 2 Exchange Rate (Q) 3dB, 4dB or 5dB 3dB Criterion Time 8hrs, 12hrs, 16hrs or 18hrs 8 hours Criterion Level 80dB, 85dB or 90dB 85dB Threshold None, 80dB or 90dB None Time Weighting None or S (Slow) None All of these configuration options can be selected from the RC:110A Reader Unit. In addition, the NoiseTools software allows user defined configurations to be loaded into the Reader Unit. The software includes preset configurations such as ISO, OSHA, ACGIH and US ACHPPM. A system can be started with a single dosebadge and a Reader unit, and expanded by purchasing additional dosebadges and the appropriate number of charging units. A range of additional external charging units allow a system to be expanded simply and easily without any of the components becoming obsolete. This manual describes the operation of the CR:110A dosebadge unit and RC:110A dosebadge Reader. Also described are the optional RC:101A Keyfob Remote Control and the UA:100 Windshield. The Keyfob allows the dosebadge to be started and stopped without the RC:110A unit, and should be ordered separately.

9 CR:110A dosebadge User Manual Page 9 Please note that the RC:110A Reader unit supports all previous versions of the dosebadge Personal Noise Dosemeter. However some features and functions may not be available when using the RC:110A Reader with previous versions (CR:100A or CR:100B) of the dosebadge. Please refer to Checking the Configuration on page 18 and Configuration of the Measurement Parameters on page 37 for more information. Also refer to Section 7 Troubleshooting on page 51.

10 Page 10 CR:110A dosebadge User Manual How the dosebadge works The dosebadge is controlled by the Reader unit through an Infrared link. The link between the dosebadge and the Reader is used to send information in a similar way to a television remote control. The RC:101A Keyfob also provides a method to start and stop the dosebadge without using the Reader unit. Each dosebadge contains a rechargeable battery which powers the unit throughout the measurement period. Each charge of the battery is designed for one measurement. The battery contains sufficient power to carry out a single measurement for over 20 hours although the dosebadge will run for much longer provided the battery is fully charged. Please note that although the RC:110A Reader unit can be used to control the previous CR:100A and CR:100B dosebadges, if the user attempts to program an older dosebadge with a configuration that is not supported, an error message will be displayed when the dosebadge is reset or data is read from the dosebadge.

46 Page 46 CR:110A dosebadge User Manual Downloading measurements to a PC Measurements that have been stored in the Reader unit can be downloaded to a PC using the NoiseTools software. The NoiseTools software automatically recognises an RC:110A Reader unit and allows measurements to be downloaded, analysed and measurement reports created. NoiseTools is supplied on a CD-ROM require a PC running Microsoft Windows XP SP3 or later. A USB communications port is required for connection to the RC:110A Reader unit via the supplied USB Cable. To install the software: 1. Insert the Disc in the CD-ROM drive 2. Follow the instructions on the screen If the installation program does not automatically start, run d:\setup.exe program from the Start, Run option in the task bar where d is the letter of the CD-ROM drive. Please note that if you are running on a network, you may need to contact your network administrator to ensure that you have sufficient access rights to install this software. This software should be installed with full administration rights to ensure that the configuration of the software can be completed. Cirrus Research plc accepts no responsibility for the installation of this software on systems where full access rights are not available. Connecting the Reader to a PC The Reader unit must be connected to a PC to allow measurements to be downloaded to the software. The Reader unit is supplied with a USB Cable which must be used to download the information. The USB Cable can only be inserted into the Communications socket in one orientation. If the connector will not fit into the socket do not force it. Ensure that the orientation of the connector is correct and that the arrow on the cable is pointing downwards. When the cable has been connected to the Reader and the PC, ensure that the Reader is switched on. If the NoiseTools software program is running, it will automatically detect the Reader unit and allow the measurements to be downloaded. Once the connection is made, the measurements can be downloaded. For more information, please refer to the NoiseTools software for more information.

47 dosebadge User Manual Page 47 Section 6 Maintenance & Care Annual Verification & Servicing It is strongly recommended that all dosebadges and Readers are returned to Cirrus or an authorised service centre at least every 12 months for verification, calibration and servicing. This should only be carried out by Cirrus Research plc or a service centre authorised by Cirrus Research plc for the service and calibration of the dosebadge. The date that the Reader and dosebadges are due for "recalibration" can be seen on the print-out and in data transferred to the computer. Cleaning The dosebadge, Reader and Keyfob should only be cleaned with a damp, lightly soaped cloth. No solvent based cleaners should be used as they may damage the dosebadge window or the case labels. The dosebadge microphone grill must be protected against soiling as blocked grill holes can deteriorate the performance of the unit. Attempting to remove dirt from these holes with sharp implements can damage the sensitive membrane underneath. The RC:110A Reader Unit should be cleaned with a damp cloth only. Ensure that the Infrared port and the Acoustic Calibrator are free from damage and dirt. Do not insert any sharp objects into the Acoustic Calibrator. Storing the dosebadge If the dosebadge is left unused for a period of time longer than a few days, it is recommended that the dosebadge be fully charged. This will avoid any potential damage to the internal batteries through unwanted discharge. If the dosebadge is not used for 1 hour, it will go into Sleep mode to protect the internal battery and to prolong the operating life. To use the dosebadge, the Shake-to- Wake sensor must be activated. Please refer to page 22 for details. If the dosebadge is left unused, the internal batteries in the badge must be left charged. When fully charged and not used, the badge battery will remain charged for at least 14 days. If the unit is stored longer than this and the batteries are left to become totally discharged, THEY WILL EVENTUALLY BE DAMAGED. To ensure optimum operation, dosebadges that have not been used for one month should be recharged. To prevent damage please ensure that the dosebadges are recharged every 2 weeks (14 days).

48 Page 48 dosebadge User Manual Cycle Charge of the dosebadge Battery The CU:110A Charger Unit provides a Discharge/Charge cycle that allows the performance of the battery to kept at an optimum level. This cycle fully discharges the battery before charging. Please note that this is not the normal operation of the CU:110 Charger Unit. To carry our this charge cycle, connect the dosebadges to the CU:110A Charger and connect the power supply. Press the Discharge/Charge cycle button located on the bottom of the charger as shown below. If you press the button through the hole on the bottom of the charger, it will discharge all badges that are currently connected, then charge them. This can take up to about 6 hours depending on the battery type and initial charge state. The internal NiMH (Nickel Metal Hydride) battery, like all rechargeable batteries, will self discharge. When arranged into a battery the individual cells within the battery, not being identical, will not all discharge at the same rate. This means that the first cell to discharge may be forced into a 'reverse current' situation by the other cells and will be damaged. If the batteries are simply left discharged, there is no way of preventing this as the discharge is within the cell. Even if they are removed from the dosebadge the self-discharge will still occur. To prevent this, it is recommended that the badge be charged monthly when not being used for measurements. If the dosebadges are left on a charger without power, the dosebadges will discharge. To ensure that the dosebadges do not discharge, remove them from the Charger unit when the Charger is not connected to the power supply. Changing the Reader Batteries The dosebadge Reader unit shows the battery level in the top right hand corner of the display as shown below. The figure on the left below shows a full battery level and the figure on the right shows the battery level at 10% of the full capacity.

49 dosebadge User Manual Page 49 The batteries for the RC:110A Reader unit are located under the black cover on the back of the instrument. Before changing the main batteries, ensure that the Reader is switched off. The memory of the Reader unit is protected when the batteries are removed. The clock of the Reader will be reset after 15 minutes when the batteries are removed. Locate the battery compartment cover and remove it from the instrument. Remove the batteries from the Reader unit and replace with batteries of equivalent type and quality. The battery should be of alkaline type AA (LR6 / AM3 / MN1500 / Mignon). Ensure that the polarity of the batteries is correct. Replace the battery cover and switch the Reader unit on. Additional information regarding the calibration of the dosebadge is provided in Appendix 3 dosebadge Calibration on page 63.

54 Page 54 dosebadge User Manual Section 8 Glossary & Terminology The following section lists the acoustic terminology that is found in this manual and in the CR:110A dosebadge Personal Noise Dosemeter and RC:110A Reader Unit. For further information, please contact your local representative or Cirrus Research plc directly. Terminology The dosebadge and Reader can produce the following metrics as defined in the relevant standards. Some of these are available on the Reader display, others require a printer or the computer software supplied. When the data is downloaded from the RC:110A Reader unit to the dosebadge software, the following parameters are provided: L Aeq The level which, if maintained constant for the same period as the measurement, would contain the same amount of energy as the fluctuating noise level. "A" weighted and expressed in decibels (dba). Doubling the energy results in a 3dB change in the L eq. This is denoted by Q=3. The Threshold used in the calculation of L AVG (see below) is not used for the calculation of L Aeq. For example: If the noise level in a factory was a constant 85dB and the measurement period was 4 hours, the L Aeq would be 85dB(A). L AVG L AVG is the average Sound Level over the measurement period when the exchange rate (Q) is other than 3dB or where there is a Threshold applied or a Time Weighting applied. L AVG is the equivalent of L eq for exchange rates other than 3dB, for example Q=5. The Threshold value is used during the calculation of L AVG with any levels below the threshold not being included. For example: Assume the threshold level is set to 80dB and the exchange rate is 5dB (which are the settings for OSHA's Hearing Conservation Amendment). If a one hour measurement was taken in an environment where the noise levels varied between 50dB and 70dB, the sound level would never exceed the threshold level and the instrument would record no value for the L AVG. If the sound level exceeded the 80dB threshold for only a few seconds, then only these seconds would contribute to the L AVG giving a level of around 40dB which is much lower than the actual ambient sound levels in the environment. L EP,d The L EP,d is the average of the measured L eq over an eight hour period. The L EP,d will be lower than the L eq when the measurement duration is less than eight hours, equal to

55 dosebadge User Manual Page 55 the L eq for a measurement of eight hours, and higher than the L eq for measurements over eight hours. For example: If a noise measurement was made for 4 hours and the L Aeq value was 90dB(A), the L EP,d value would be calculated to be 87dB(A) as the measurement duration is half the Criterion Time of 8 hours and the exchange rate is 3dB. L EX,8h Under the EU Physical Agents (Noise) Directive which will be introduced in member states of the EU by February 2006, the terminology for the Daily Personal Noise Level or L EP,d has been changed to be L EX,8h. The calculation is the same and the data is calculated from the LAeq and Measurement Duration in the same way as for L EP,d. TWA The Time Weighted Average is the average of the measured L AVG over an eight hour period. The TWA will be lower than the L AVG when the measurement duration is less than eight hours, equal to the L AVG for a measurement of eight hours, and higher than the L AVG for measurements over eight hours. % Dose A percentage of a fixed dose value based on the criterion level and criterion time. The criterion level and time are set by local standards. For example, some Regulations may mandate the use of 85dB for 8 hours as the limit for a daily noise exposure. If the noise level was a constant 85dB for 8 hours, this would generate a % Dose of 100%. Estimated Dose Estimates the % dose (described above) that would have been received by the wearer if the average level measured had existed for the period defined by the criterion time. For example, if for a 4 hour measurement the % Dose was 50%, the Estimated Dose would be 100% for the 8 hours of the Criterion Time. Exposure (Pa s, Pa hr) The noise exposure expressed in linear terms rather than using the logarithmic db unit or % dose. Expressed in Pascal squared hours (Pa hr) or Pascal squared seconds (Pa s). Estimated Exposure Estimates the exposure (described above) that would have been received by the wearer if the average level measured had existed for the period defined by the criterion time. Expressed in Pascal squared hours (Pa hr). L AE or SEL

56 Page 56 dosebadge User Manual The level which, if maintained constant for a period of 1 second would have the same sound energy as that actually received by the dosebadge during the measurement period. For example, if the measurement duration was 8 hours and the L eq was 85dB(A), the L AE would represent all of the noise energy over the 8 hour period squashed into a duration of 1 second. L AE is the same as SEL (Sound Exposure Level) Threshold Sound Levels below the threshold are excluded from all averaging. For example, OSHA measurements use an 80dB threshold and call for a hearing conservation program to be implemented when the eight hour TWA exceeds 85dB (50% dose). Criterion Level (CL) In db, the normalised eight hour average weighted sound level the corresponds to the maximum permitted daily exposure or 100% noise dose. Criterion Time (CT) The time, in hours, used in the calculation of the % Dose and Estimated % Dose measurement parameters. By default, this is set to 8 hours but can be configured to other durations in the Reader unit. Peak The true peak level of the pressure wave (not the highest sound pressure level which is termed the L max). The CR:110A dosebadge measures the true Peak level.

General Field Grade for Sound Level Meters.Personal Noise Dosemeters to the IEC Standard do not have a Class or Type. Time Weighted Average. The daily personal exposure level calculated from the LAVG and the measurement duration. TWA replaces LEP,d in the OSHA Q=5 version of the dosebadge. LAVG The continuous A weighted sound level measured over the measurement period with an exchange rate of 5dB. LAVG replaced Leq in the OSHA Q=5 version of the dosebadge. % Dose The noise level measured expressed as a percentage of a fixed level. For example, the reference 100% level would be a continuous level of 90dB for 8 hours. The Criterion Time (CT) and Criterion Level (CL) are used for the 8 hours and 90dB level. % Estimated Dose The % Dose projected forward over an 8 hour duration, assuming that the noise level continued at the same level for the rest of the 8 hour reference period. The Criterion Time (CT) and Criterion Level (CL) are used for the 8 hours and 90dB level. Exposure in Pa 2 hr Estimated Exposure in Pa 2 hr The noise level measured expressed in as a linear term in Pa 2 hr (Pascal Squared Hours). For example, a noise level of 94dB for 4 hours would be 1Pa 2 x 4 hours (94dB = 1Pa) giving an Exposure of 4 Pa 2 hr. The 8 hour period is taken from the Criterion Time (CT). The Noise Exposure above projected forward over an 8 hour duration, assuming that the noise level continued at the same level for the rest of the 8 hour period. The 8 hour period is taken from the Criterion Time (CT).

63 Appendix 3 dosebadge Calibration dosebadge User Manual Page 63 As with all noise instruments, calibration is an essential part of the process of making a measurement and helps to ensure that your measurements are accurate and valid. It also helps to ensure that your equipment is operating correctly. When calibrating your noise measurement instruments, you should always follow the instructions and information provided by the manufacturer. This section provides detailed information regarding the calibration of the dosebadge system. First Calibration The initial calibration of the dosebadge, after the unit has been reset by the RC:110A Reader, is the only one that affects the measurement data. The second calibration, which is made after the measurement had been completed, is a check that the calibration level is within acceptable tolerances. Resetting the dosebadge prepares it for a new measurement by clearing all previous data, ensuring the time and date are correct, setting the required measurement parameters and clearing any previous calibration offsets or corrections. The first calibration is conducted by applying a fixed sound pressure level of 114dB to the dosebadge from the RC:110A Reader, internally reading the levels reported by the dosebadge and then storing a calibration offset within the dosebadge. This calibration offset is subsequently used by the Reader to correct the data measured. There is no user requirement to apply this offset as it is applies automatic by the dosebadge. All the data reported by the Reader and the NoiseTools software is already corrected and no further corrections or adjustments are needed. Calibration offsets between +/-3.0dB are accepted within the dosebadge. Second Calibration Once the first calibration has been carried out, any subsequent calibration will follow the same process expect that a new calibration offset is not stored nor applied. Subsequent calibrations are checks only and do not affect the measurement data (only the calibration offset from the first calibration is applied). The Reader device reports subsequent calibrations as a 'drift'. The drift is considered to be the difference between the actual calibration offset (from the first calibration) and the notional offset from subsequent calibration checks. There is no limit to the amount of drift reported by the second calibration. For example:

64 Page 64 dosebadge User Manual First Calibration Level of Reader calibrator = 114,0dB 1st calibration level reported to Reader by dosebadge = 114,1dB. Calibration Offset = -0,1dB. (114,0 114,1) The Reader will correct all data from this dosebadge by -0,1dB until the next time that the dosebadge is reset and recalibrated. Second Calibration Level of Reader calibrator = 114,0dB 2nd calibration level reported to Reader by dosebadge = 113,9dB. Drift = 0,2dB. (114,1dB 113,0dB) The Reader will correct all data from this dosebadge by -0,1dB until the dosebadge is reset. Second Calibration and Drift In most applications, drifts of between +/-0,5dB are acceptable; that is that the second calibration check differs from the first calibration results by up to +/-0,5dB. Drift can occur for a number of reasons, some of which are: 1. A temperature change between the 1st and 2nd calibration in either the dosebadge or Reader. 2. A barometric pressure change between the 1st and 2nd calibration in either the dosebadge or Reader. 3. A relative humidity change between the 1st and 2nd calibration in either the dosebadge or Reader. 4. Battery level in the dosebadge. The dosebadge Reader contains an acoustic calibrator and sensors which compensate for temperature, pressure and humidity. This ensures that the calibration level provided by the Reader unit is consistent. However the dosebadge may not be at the same temperature, pressure or humidity as the Reader at the point of calibration. It is important that both the dosebadge and Reader are left together, in the same environment, for a period of at least 30 minutes prior to calibration. This allows the temperature of both the Reader and the dosebadge to stabilise. Recommended calibration procedure The recommended process for both first and second calibrations is as follows:

65 dosebadge User Manual Page Charge the dosebadge battery using the CU:110A charger in the same vicinity as the RC:110A Reader. 2. Once fully charged, remove the dosebadge from the CU:110A charger for a period of roughly 5 to 10 minutes. 3. Calibrate the dosebadge using the RC:110A Reader. 4. Carry out the measurement 5. Stop the dosebadge. 6. Charge the dosebadge before carrying out the second calibration and downloading the measurement data. If the recommended battery recharge cannot be conducted after a long measurement then leave the dosebadge in the same environment as the Reader for at least 30 minutes so that both units are stable and matched for environmental conditions.

66 Page 66 dosebadge User Manual Appendix 4 Resetting the dosebadge and Reader Unit Resetting the dosebadge If, in the event that the dosebadge does not respond correctly to commands from the Reader Unit and if all of the troubleshooting steps have been followed, this reset procedure can be followed. This procedure should only be followed if the CR:110A dosebadge does not respond to commands from the RC:110A Reader Unit. Please ensure that all of the troubleshooting listed above has been followed before carrying out this procedure. In particular, ensure that the section covering the Shake-to-Wake function has been read and understood. Please contact Cirrus Research plc or your local distributor for further details. The purpose of this procedure to perform a hard reset on a CR:110A (dosebadge). This procedure should only be followed, if you have been instructed to do so by Cirrus Research, on an individual unit. The actions described in this procedure should not erase any data from your dosebadge unit, but Cirrus Research plc do not take any responsibility for loss of data or any damage that occurs to your dosebadge from following this procedure. Please fully read and make sure you understand the whole procedure before starting it. If you do not feel confident about following the procedure, please do not attempt it! Warnings This symbol is used throughout this procedure to indicate that special attention should be taken and any instructions followed carefully. 1. With a small, high quality Philips PH00 screwdriver remove the three screws from the base of the dosebadge. SCREWS 2. Place the metal label and three screws to one side.

67 dosebadge User Manual Page 67 These screws are extremely small and easily lost. Please place them in small container or similar. 3. Take a thin small metal object (a pin or bent open paperclip is ideal) and insert it into the hole highlighted blue in the picture below. Care must be taken to insure that it is the correct hole. Use the locating pin in the case and the notch in the baseplate as a reference. RESET 4. Move the metal object in the hole until you see the Blue LED flash through the optical window on the dosebadge. What you are trying to do with the metal object is connect the pin directly below the hole with the silver metal baseplate. 5. Insert the dosebadge into the calibrator cavity on the top of your dosebadge reader. Test the dosebadge is now communicating. 6. Place the metal label back onto the bottom of the dosebadge. Rotate the label until all three holes are lined up. Care must be taken lining up the three holes. If all three holes are not lined up, rotate the metal label further. Inserting a screw into the incorrect hole could seriously damage your dosebadge! 7. Carefully place the three small screws through the holes in the metal label and screw them into the baseplate. DO NOT over tighten the three small screws as damage to their heads will occur. 8. Place the dosebadge onto a CU:10xA charger, and allow the dosebadge to go through a full charge cycle before using.
